As the grand Imperator of Highmaul, Mar'gok is descended from a long line of sorcerers who have ruled the Gorian Empire. Equal parts cunning and brutality, Mar'gok recognized the rising tide of the Iron Horde and what it would mean to oppose them. He has acquiesced to an alliance with Grommash, even as he continues to search for a way to tip the balance of power back into his favor.

Accelerated Assault will stack indefinitely until Imperator Mar'gok melee attacks a different target.

Mark of Chaos will inflict damage to allies within 35 yards when it expires.

Imperator Mar'gok will periodically summon Arcane Aberrations.

Phase 1: Might of the Crown

Arcane Wrath - Imperator Mar'gok blasts a random player with Arcane energy, branding them for 4 sec. When Branded expires it inflicts 46,400 Arcane damage to the wearer and jumps to their closest ally within 200 yards. Each time Arcane Wrath jumps, its damage increases by 25% and range decreases by 50%.

Destructive Resonance - Imperator Mar'gok summons an Arcane mine that persists for 1 minute. If triggered, Destructive Resonance inflicts 84,000 Arcane damage to all players. In addition, this effect inflicts 140,000 Arcane damage to the player that triggered it, increasing their Arcane damage taken by 45% for 60 sec and stunning them for 1.5 sec whenever they take Arcane damage.

In Mythic difficulty, Imperator Mar'gok begins the fight with both the Rune of Displacement and Rune of Replication active.

Arcane Wrath: Displacement - In addition to Arcane Wrath's normal effects, Branded Players are unable to move more than 10 yards from the location they were marked. Attempting to leave the marked area will teleport the player back to the location they were originally marked.

Mark of Chaos: Replication - In addition to Mark of Chaos' normal effects, 8 Orbs of Chaos are conjured when Mark of Chaos expires. Each orb flies out from the wearer and inflicts 143,000 Arcane damage to all players that they move through.

Force Nova: Replication - In addition to Force Nova's normal effects, players who are damaged by Force Nova will inflict 12,500 Arcane damage to their allies within 4 yards.
